Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor for preparing a sustained-release controlled-release dry suspension. Background Art

[0002] When using micro-nano coating technology to prepare tilmicosin dry suspension, a reactor is needed to mix the liquid with the powder solid. The traditional reactor generally only has a shell and an internal stirring structure.

In addition, during the stirring and mixing process, some undissolved materials that are easy to adhere are easy to adhere to the inner wall of the reactor and the stirring part, which makes subsequent cleaning more troublesome. Therefore, how to solve these problems needs to be considered. Utility Model Content
